It has been developed for advanced, low-power Features: applications such as personal communications or data acquisition. This device also has a page write capabil- Single Supply with Operation down to 1.7V for ity of up to 64 bytes of data. This device is capable of 24AA128/24FC128 devices, 2.5V for 24LC128 both random and sequential reads up to the 128K Devices boundary. Functional address lines allow up to eight Low-Power CMOS Technology: devices on the same bus, for up to 1 Mbit address - Write current 3 mA, typical space. This device is available in the standard 8-pin plastic DIP, SOIC (3.90 mm and 5.28 mm), TSSOP, - Standby current 100 nA, typical 2 MSOP, DFN, TDFN and Chip Scale packages. 2-Wire Serial Interface, I C Compatible Cascadable up to Eight Devices Block Diagram Schmitt Trigger Inputs for Noise Suppression A0 A1 A2WP HV Generator Output Slope Control to Eliminate Ground Bounce 100 kHz and 400 kHz Clock Compatibility 1 MHz Clock for FC Versions I/O Memory EEPROM Control Control XDEC Page Write Time 5 ms, typical Array Logic Logic Self-Timed Erase/Write Cycle Page Latches 64-Byte Page Write Buffer I/O Hardware Write-Protect SCL YDEC ESD Protection >4000V SDA More than 1 Million Erase/Write Cycles Data Retention > 200 years VCC Factory Programming Available Sense Amp.
